I like rubber recoil pads for how they protect the butt, not always for recoil reduction. For dove shooting, none is needed and a couple of my dove guns have checkered butts. But, for ducks, in blinds and boats and flooded timber, I like a recoil pad. It protects the butt and helps keep it out of the inevitable 1/2" of water in the bottom of all pit blinds and duck boats. For serious clays work...............recoil pad. For quail ...............doesn't matter. For turkeys ..............no big deal either way.
